Expert writing Tips
Best practice
When indicating a sequence of events, choose either "after" or "since" based on the intended meaning. "After" is used to indicate that one event follows another, while "since" indicates a duration of time from a past event to the present.
Common error
Do not combine "after" and "since" as they both serve as temporal markers and using them together creates redundancy and grammatical errors. Select the single word that best fits the context.
